Setting Global Data Flow Project Options

Use the Global Data Flow tab of the Project Options window to specify whether data flow diagrams include literals, variable values set at initialization, and Unisys Cobol common storage variables; whether they show incoming, outgoing, and recursive data flows; and the number of nodes they display.
  1. Choose Options > Project Options. The Project Options window opens. Click the Global Data Flow tab.
  2. In the Relationships pane, choose any combination of:
    • Literal Flow to include literals in the data flow diagram for the selected variable
    • Initial Values to include variable values set at initialization in the data flow diagram for the selected variable.
    • Common Area Transition to include Unisys Cobol common storage variables in the data flow diagram for the selected variable. Common storage variables are not explicitly declared in CALL statements.
    Note: To include Unisys Cobol common storage variables, you must have verified the project with the Perform Unisys Common-Storage Analysis option set in the project verification options.
  3. In the Directions pane, choose any combination of:
    • Causes to generate data flows into the selected variable.
    • Consequences to generate data flows from the selected variable.
    • Self-Dependencies to show recursive data flows for the selected variable.
  4. In the Node Limit combo box, enter the maximum number of diagram nodes you want to display. You might restrict the number of nodes to improve performance or make the diagram easier to read. You can also use the slider on the Node Limit tool bar to adjust the number of displayed nodes.
    Note: All children of a parent node are displayed even if some of them exceed the specified maximum.
